A 5.98 g portion of a known compound 3-isopropoxy-4-methoxybenzaldehyde was added to 4.49 g of 4-(1,2,4-triazol-1-yl)-o-phenylenediamine obtained in Reference Example 2, and the mixture was stirred for 18 hours in 37 ml of nitrobenzene while heating at 150° C. After cooling, nitrobenzene was evaporated under a reduced pressure. By crystallizing the resulting residue with ethyl acetate/hexane, 4.90 g (55%) of the title compound was obtained. Its physical property values are shown as the Compound No. 1 in Table 1.
